Question

If 5p = -100 + 3Q^2, which of the following could Q possibly be?

Answer 1

Q = square root of 5 times p minus 100 over 3
Q = square root of 5 times p plus 100 over 3
Q = square root of negative 5 times p plus 100 over 3
Q = square root of negative 5 times p minus 100 over 3

Answer 3

Answer 4

1.add 100 to both sides and then divide by 3
2. take the squareroot

Answer 5

so that would be q^2 = 100+5p/3

Answer 6

the sqrt of 100 + 5p/3 = q

Answer 7

So it would be the second one?

Answer 8

if you write fractions like that, you need to use parentheses!

\[5p = -100+3Q^2\]\[5p+100 = -100+100 + 3Q^2\]\[(5p+100)/3 = Q^2\]
\[Q = \sqrt{(5p+100)/3}\]

Answer 9

\[3 Q^2=5P+100\]
\[Q^2=\frac{ 5P+100 }{ 3 }\]
Q=?

Answer 10

100 + 5p/3 is not the same as \[\frac{100+5p}{3}\]

Answer 11

oh ok thanks you both so much for the help
